ROLLER BEARING. APPLICATION FILED JAN. 26, 1910.

HERBERT B. GILLETTE, OF GRAND RAPIDS, MICHIGAN.

ROLLER-BEARING;

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed January 25, 1910. Serial No. 540,021.

To all whom it may concern:

Be it known that I, HERBERT B. GILLETTE, a citizen of the United States,residing at Grand Rapids, Michigan, have invented certain new and usefulImprovements in Roller- Bearings, of which the following is aspecification.

This invention relates to improvements in roller bearings.

My present invention relates particularly to improvements in rollerbearings of the type shown in my application for Letters Patent, filedOct. 21, 1909, Ser. No. 523,87 9, and is a modification and in somerespects an improvement upon the structure there illustrated anddescribed.

The main objects of this invention are: First, to provide an improvedroller bearing in which the bearing rollers are so arranged that theyare free to adjust themselves into alinement and to distribute the load,and, at the same time, are retained in position without the use of cagesor journal pins for the rollers. Second, to provide an improved bearingwhich is so constructed and arranged that the wear and friction on theparts is minimized. Third, to provide an improved roller bearing inwhich the parts are simple and economical, and easily assembled anddisassembled.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The structure described constitutes one effective embodiment of myinvention. Other embodiments would be readily devised by those skilledin the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of thefeatures of my invention is clearly illustrated in the accompanyingdrawing, forming a part of this specification, in which:

Figure l is a detail side elevation of a structure embodying thefeatures of my invention, the hub and the outer bearing member beingshown in longitudinal section, the

other parts being shown in full lines. Fig. 2 is a transverse sectiontaken on a line corresponding to line 2-2 of Fig. 1, the hub beingomitted. Fig. 3 is an enlarged detail longitudinal section taken on aline corresponding to line 33 of Fig. 1, the hub being omitted, the axleand bearing rollers being shown in full lines.

In the drawings, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents a shaft or an axle such as anaxle on a vehicle. The inner bearing member 2 is adapted to receive theaxle. The outer bearing member 3 is arranged in the hub, as 1, of thevehicle wheel or pulley. These bearing members are preferably conical,as illustrated. The bearings are ordinarily arranged in pairs, the otherbearing of the pair being a substantial duplicate of the bearingillustrated is not shown, as their arrangement will be obvious to thoseskilled in the art to which this invention relates.

The bearing rollers 5 are preferably conical, as shown, being of uniformtaper from end to end, the small ends 6 being conical and provided withaxially-projecting retaining pins 7, the large ends being preferablybeveled at 8. The inner bearing member 2 is provided with anoutwardly-projecting thrust flange 9 at its large end. This flange ispreferably shouldered to form a seat 10 for the dust-excluding ring 11.A ring-like thrust bearing member 12 is preferably provided for thelarge end of the rollers. This thrust bearing member is sleeved upon theinner bearing member to rest against the shoulder 9 thereof. The bearingface 13 of the thrust ring or thrust bearing member 12 is so disposedrelative to the axes of the rollers that the rollers engage the same attheir inner edges only. The rollers are preferably beveled at 8, asstated, so that they do not present to the thrust ring a cutting orsharp edge, and at the same time, only a small contact surface is had.The retaining ring 141 is locked in position by means of the lockingring 15, the bearing member 'beingprovided with a groove 16 to receivethe same. The inner bearing member is shouldered at 17 to form a seatfor the retaining rmg, and provldes an efiectlve' means for detachablysecuring the parts together so that they can be readily assembled ordisassembled, as occasion may require. The retaining' ring is soarranged that its outer edges, and also the retaining pins 7 arenormally out-of engagement, although the edge of the ring is preferablyadapted to form a bearing for the conical portion 6 of the rollers,should they be in any manner dis-i placed from their normal operativeposition; The thrust ring is of such width that it 00- rthe bearing andto impinge each other, and

with thecone throughout the entire length of the bodies of the rollers.

. One of the main advantages of the present structure, 111 WlllCll therollers are provided with the axially-projecting retaining pins 7 attheir small ends, over that of the structure shown in my applicationreferred to is that the parts may be so arranged that the rollers arepermitted greater axial move ment. This is of some advantage inmanufacture, and further, this looseness gives the rollers greaterfreedom in alining themselves and in adjusting themselves to distributethe load. At the same time, when the outer bearing member or cone is re-7 moved, the rollers are effectively retained and may beeasily shiftedabout to permit the thorough cleaning of the cone of the rollers, if itis desired, with disassembling the rollers from the inner cone. j

' My improved bearing is very economical in structure, and is, at thesame time, a very superior structure. The load is effectivelydistributed throughout the rollers, and the wear onthe parts is reducedto a minimum.

I have'illustrat'ed my improvements inthe form in which I have embodiedthe samein practice, and which form I find to be. highly satisfactory. Iam, however, aware that the structural details may be greatly variedwithout departing from my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a bearing, the combination with an inner bearing member; an outerbearing member; conical rollers, the sides of said rollers'being ofuniform-taper from 'end to end, their large ends being beveled and theirsmall ends being conical and provided :with axially-projecting retainingpins; a thrust memberon said inner bearing member for the large ends ofsaid rollers, the bearing face of said thrust member being disposed sothat the inner edges only of said rollers contact-therewith; and aretaining ring into which the said retaining pins of said rollersproject, said pins being normally out of contact with said retaining rinthe outer edge of said retaining ring being. adapted to form a bearingfor, but being normally out of bearing engagement with the conical endsof said rollers, said thrust member being of suflicient width to coactwith said retaining ring in loosely securing said rollers to said innerbearing member.

2. In a bearing, the combination with an inner bearing member; an outerbearing member; conical rollers, the sides of said rollers being ofuniform taper from end to end, their small ends being conical andprovided with axially-projecting retaining pins; a thrust member on saidinner bearing member for the large ends of said rollers, the bearingface of said thrust member bein disposed so that the inner edges only ofsaid rollers contact therewith; and a retaining ring into which the saidretaining pins of said rollers project, said pins being normally out ofcontact with said retaining ring, the outer edge of said retaining ringbeing adapted to form a bearing for, but being i normally out of bearingengagement with the conical ends of said rollers, said thrust memberbeing of sufiicient width to coact with said retaining ring in looselysecuring said rollers to said inner bearingmember.

3.
